Looking into getting a big rifle for my mini collection. Won't get to shoot it a lot around where I live so maybe 2-3 trips a year to a 1,000+ yard range. Semi auto would be nice to soak up recoil but that drives the price into ouch territory... So... what would you go with? A 50bmg AR-15 upper? Savage 338 lapua bolt action? I think I can reload 50bmg cheaper because components are more readily available.
